1. A surgical plate comprising:
- a pre-contoured Y-shaped plate having an inferior surface and a superior surface, the plate consisting of a trunk and pair of a first arm and a second arm,the trunk having a linear medial longitudinal axis along the superior surface extending between a first and a second end;
the first arm having a first arm linear medial axis and an ear with at least one screw hole defining a first screw axis and which is a threaded locking screw hole, the first ear being attached directly to the trunk by a linking section having a waist, a first angle being defined by an intersection of the medial longitudinal axis of the trunk with the first arm linear medial axis, and a first length being defined by a line from a center of the first arm screw hole along the first arm linear medial axis to the medial longitudinal axis of the trunk, and,the second arm having a second arm linear medial axis and a second ear with at least one second screw hole defining a second screw axis and which is a threaded locking screw hole, the second ear being directly attached to the trunk by a linking section having a waist, a second angle being defined by an intersection of the medial longitudinal axis of the trunk with the second arm linear medial axis, and a second length being defined by a line from a center of the second arm screw hole along the second arm linear medial axis to the medial longitudinal axis of the trunk, and the first angle and the first length being different from the second angle and the second length whereby the first screw axis and the second screw axis converge toward the inferior side of the plate but do not intersect and wherein the first screw hole and the second screw hole are placed a radially equal distance from the medial line of the elongate central trunk.

Abstract
The present invention relates to a series of orthopedic plates for use in repair of a bone. The plate has a Y-shaped profile or an X-shaped profile which includes an elongate central trunk with a complex contour and either one or two terminal pairs of arms that have a first arm and a second arm that form differing angles and lengths relative to the trunk portion of the plate. The arms include locking screw holes where the screws converge toward each other to provide for multiplanar fixation but which do not impinge.
